Target

  • FunctionInhibits factor X (X(a)) directly and, in a Xa-dependent way, inhibits VIIa/tissue factor activity, presumably by forming a quaternary Xa/LACI/VIIa/TF complex. It possesses an antithrombotic action and also the ability to associate with lipoproteins in plasma.
  • Tissue specificityMostly in endothelial cells.
  • Sequence similaritiesContains 3 BPTI/Kunitz inhibitor domains.
  • DomainThis inhibitor contains three inhibitory domains. The first domain interacts with VIIa and TF, the second one with Xa.
  • Post-translational
    modifications
    O-glycosylated.
  • Cellular localizationSecreted.
